Thermoelectric properties such as electrical conductivity and Seebeck coefficient have been measured in a temperature range 11-373 K using Harman technique. At the room temperature, the Z parameter has been calculated as 4.1x10-3 K-1 and 2.4x10-3 K-1 for the samples grown by the traveling heater methods, respectively. KW - Key Words: Traveling heater and heat pressing methods KW - Harman technique KW - thermoelectric properties N2 - İki adet n-tipi (Bi2Te3)Se3 yarıiletkeni Bi2Te3 ve Bi2Se3 bileşimlerinden, bölge eritme ve presleme yöntemi ile büyütüldü. Bu yarıiletken numunelerin termoelektrik özellikleri; elektriksel iletkenlik ve Seebeck kat sayısı 11-373 K sıcaklık aralığında Harman tekniği kullanılarak ölçüldü. Oda sıcaklığında, Z parametresi bölge eritme yöntemi ile büyütülen numune için 4,1x10-3 K-1presleme yöntemi ile büyütülen yarıiletken numune için 2,4x10-3 K-1 olarak hesaplandı CR - http://www.melcor.com homepage of Melcor, USA (2004) CR - Bowley A.
